Here's a detailed mathematical review of Hammond tonewheel harmonics
vs equal temperament. I'm sure many here have seen this page.

I'd say that anyone who has created a synth patch with this in mind
is making a better "clonewheel" than some of the rompler clonewheels
out there and you will avoid the "beating" problems inherent in this
approach.

In my mind, a clonewheel synth should be modeled as close to a real
tonewheel as possible, but that shouldn't exclude using samplers or
synthesizers if the intonation and other things like percussion are
handled correctly in the same manner as a real Hammond. I've made
some pretty killer Hammond M1 patches on my Jupiter 8 that are would
be almost dead on if it weren't for the intonation being off.
However, getting all the harmonics partials to mix and overlap
correctly is best left to a tonewheel model.

But if you are using a synth and trying to get clonewheel sounds, go
digging for the user tuning tables and make one for your Hammond
patches. You may find that you like to use it on some of your other
sounds too as it makes many chords sound really really good. A "good"
synthesizer, though should be able to model anything and I think some
of the Korg synths do come quite close to achieving that from a
technical perspective if not an aural one.

In my opinion, a bad leslie effect will do more to kill the realness
a clonewheel patch than the patch itself. Please forgive me if we are
only to be discussing synthesizers marketed as "tonewheel organ
emulations" in this group, as I'm new here. -pc

P.S. If anyone is really interested and can't figure it out from the
link at the top of this message, I can post the settings of my custom
X5 intonation map. They should be good or any Korg AI synth, or
anything else which allows for a user-defined scale.
